fig. 4 is a schematic structural diagram of the rubber nozzle check valve embodiment 2 of the coffee machine of the present invention.

In the figure: the valve comprises a valve body 1, a valve core 2, a pipeline joint 3, a buffer booster ring 4, a sealing ring 5, a mounting hole 10, a first flow hole 11, a second flow hole 12, a core shell 20, a valve nozzle 21, a sealing groove 22, an inner hole 40, a liquid inlet hole 200 and an overflowing gap 210.

Detailed Description

The present invention will be further explained with reference to the drawings and examples.

Example 1:

the rubber nozzle check valve of the coffee machine described in this embodiment, as shown in fig. 1, it includes a valve body 1 and a valve core 2, the valve body 1 is provided with a mounting hole 10, a first flow hole 11 and a second flow hole 12 which are communicated with each other, the valve core 2 is hermetically connected in the mounting hole 10, and the rubber nozzle check valve is characterized in that the valve core 2 is composed of a core shell 20 and a valve nozzle 21, the core shell 20 is provided with a liquid inlet hole 200, the valve nozzle 21 is a cap-shaped duckbilled elastic member, a protruding end of the valve nozzle faces the first flow hole 11 and the second flow hole 12, a normally closed flow hole is arranged in the valve nozzle 21, the bottom of the valve nozzle is fixed on the liquid inlet hole 200, and when the flow hole 210 opens, the liquid inlet hole 200 is communicated with the first flow hole 11 and the second.

In order to ensure the sealing between the valve core 2 and the valve body 1, as shown in fig. 1 and 2, a sealing groove 22 is provided on the outer ring of the valve core 2, and a sealing ring 5 is provided between the sealing groove 22 and the valve body 1.

In the actual working process, the first flow hole 11 and the second flow hole 12 are respectively connected with two hydraulic pumps, the liquid inlet hole 200 is immersed in a container for storing liquid, when the liquid circulates between the hydraulic pumps, the liquid flows into the valve from the first flow hole 11 and then flows out along the second flow hole 12, as shown in fig. 2, the valve mouth 21 is closed under the pressure of the liquid, so that the flow passage between the container and the two hydraulic pumps is disconnected; when the hydraulic pump connected to the first flow hole 11 stops working, the liquid in the container is sucked into the check valve and rushes out the flow slit 210 to flow along the second flow hole 12, as shown in fig. 3.
